Are you using Google Voice (s goog) with more than one phone, like I am? If so, you might find this tip to be very handy. Aside from that, I think it’s totally cool and I can’t wait to actually try it! To switch phones while on a Google Voice call, you simply hit the * button on the handset you’re using. Once you do that, Google Voice will ring the other phones on your account. You just answer that call on one of the other phones and your original conversation will seamlessly switch to that handset. In fact, your caller will be none the wiser that you switched devices.
This only works on incoming Google Voice calls at the moment, so don’t try it with an outgoing conversation. I just pinged someone to call me just so I can see how well it does, or doesn’t, work. I’m hoping it does work well because it would be useful if had Google Voice ringing the wrong phone or if that particular handset’s battery were running low.
